This is like a lab experiment demonstrating what will unfold for the rest of the country if these gun bans and registration laws ever take effect.“This program has been in place for more than a year and is aimed only at getting illegal crime guns off the streets: a goal that every New Yorker can agree with,” wrote Janine Kava, director of public information at NYS DCJS.
It is unlikely the police would ever engage in any kind of door-to-door mass searches and confiscations like what happened in certain parts of New Orleans. The more likely approach will be using the registration lists for targeted confiscation, combined with this kind of propaganda/incentive approach of "only at getting illegal guns off the streets".
